WATER-CLOSET VENTILATOR.

Application filed. February 9, 1924. Serial No. 691,550.

T aZZ whom it may concern.

Be it known that I, Jnssn O. Jnrrnms, a citizen of the United States,residing at Big Creek, in the county of Fresno and State of California,have invented certain new and useful Improvements in lVa ter-ClosetVentilators, of which the following is a specification.

This invention is a ventilator adapted to be attached to a water closetfor withdrawal of foul air from the bowl; and it is the object of theinvention to provide an extremely simple and compact construction,including a fan for withdrawing the foul air, and a water motor foroperating the same, said fan and motor being positioned below theflooring upon which the water closet stands, with a valve controllingthe flow of said water motor, mounted on the closet bowl in rear of theseat, so as to be actuated by raising the cover for said seat.

It is a further object of the invention to withdraw the foul air fromthe water closet through a flattened air chamber projecting between thecloset seat and the rim of the closet bowl so as to open into said bowl,the air chamber communicating with the suction fan through a conduitextending upwardly from said fan, and having a forked upper endstraddling the flushing pipe for the closet bowl and connected to saidair chamber.

It a still further object of the invention to provide an extremelysimple but practical valve mechanism controlling the flow to the watermotor, said valve mecha nism including a casing mounted in the flattenedair chamber in rear of the closet seat, so that the valve stemprojecting from said casing may be actuated by an operating member fixedrelative to the swinging closet seat cover, and said valve casing havingintake and discharge'pipes for the flow to the ater motor, extendingdownwardly on opposite sides of the flushing pipe for the closet bowl,to a source of water supply and to the water motor respectively.

It is a still further object of the invention to provide simplifiedmeans for opening the water control valve by raising the seat cover,said operating means including a cam fixed upon a usual hinge rodjournaled at the rear of the closet bowl, the seat for the closet bowlbeing loosely journaled on said hinge-rod, and the seat cover beingfixed to said rod, so that lifting said cover will turn the hinge rodand the cam fixed thereto, to cause engagement of said cam with the stemof the water control valve.

Further objects of the invention will be readily understood from thefollowing description of the accompanying drawings, in which: v

Fig. 1 is a side elevation of a water closet having the improvedventilator attached thereto. i

Fig. 2 is a rear elevation of the same.

Fig. 3 is a detail section on the line 3-3 of Fig. 1.

Fig. 4 is a fragmentary plan view of the water closet and ventilator.

Fig. 5 is a vertical section on the line 55 of Fig. 4:.

The water closet having the improved ventilator attached thereto,comprises a usual bowl-1, provided with a drain 2, and a flushing pipe 3projecting rearwardly and upwardly from the rear of the bowl. A hingedseat 4 .is spaced from the rim of the bowlby usual bumpers 5, and saidseat is provided with a usualhinged cover 6.

The hinge mechanism for the seat and its cover comprises bearing bolts 7fixed on the rear portion of the rim of the bowl at the respective sidesthereof, with a hinge rod 8 journaled in said bearings and extendingacross the rear of the closet bowl. Bearing brackets 9, fixed to theseat of the closet, are loosely journaled on rod 8, and brackets 10fixed to said rod and extending forward therefrom, are secured to theseat cover, so that raising said cover will turn the hinge rod. I

A. cam 11 is fixed to and extends rearwardly from the hinge rod,preferably midway of its length, the cam being adapted to engage thecontrol valve of the ventilator, when the hinge rod is turned by liftingthe seat cover, in order to open said valve and create a suctionthrough. the ventilator, as will be hereinafter described.

The ventilator comprises a flattened snetion chamber 12, mounted on therear of the closet bowl and extending forward between the rim of thebowl and the seat 4., said chamber being open at its front end whichprojects into the closet bowl, so that the foul air from the bowl may bedrawn into said chamber. The suction chamber is provided with laterallyextending ears 13 adapted to be engaged by hearing bolts 7, forretaining the chamber in place upon the closet bowl.

A conduit 14 extending vertically in rear of the closet bowl, has aforked upper end to form a suction chamber 15 into which conduit 14opens, and a housing 16 at the opposite end of said casing.

A shaft 17 is journaled axially in the cylindrical casing, with a fan 18fixed on i said shaft in suction chamber 15,1 and a water motor 19secured to said shaft in housing 16. The air drawn into suction chamber15 by the fan is discharged through a conduit 20 extent ing from theperiphery of-said chamber to a usual vent (not shown). A nozzle 21 fordischar ing water against water motor 19, is mounte in the periphery ofhousing 16, and a water discharge conduit 22 extends radially from thebottom of said housing and is preferably connected to "the drain 2 ofthe closet bowl.

It will thus be seen that flow of water through nozzle 21 will turn thewater motor and the suction fan, "and thereby create a suction throughconduit 14 and air chamber 12, for withdrawing foul air from the close tbowl.

' stem in the space The valve mechanism actuated by cam 11, andcontrolling how of water through nozzle 21 to the water motor, comprisesac'lose'd' casing 23 mounted in chamber 12 in rear of cam 11, andpreferably extending above said chamber. This casing has a horizontalpartition i24 forming a valve seat, and a second partition v25 spacedabove the same an forming a guide for valve stem 26 which extendsthrough a suitable smiling box. 27. The valve stem has a valve head 28cooperating with valve seat 24, and is proi'fide'd at its upper end witha plunger '29 projecting through the top ofcasing 23, so as to bedepressed by cam 11 when the seat cover is raised.

A coil spring 30 is mounted on the valve between partition 25 and thetop of casing 23, said spring, abutting against plunger 29 so as tonormally elevate the valve stem and'c' lose the valve, but being adaptedto yield to permit opening of the valve when plunger 29 is de pressed bycam 11.

Pipes 31 and 32 communicate with the spaces formed in the valve casingabove and below valve seat artition 24, said pipes extending rearwai lyfrom casing 23 and do'nmwardly and outwardly through air 32 is connectedto a suitable source of wa- 'ter supply (not shown). It will thus beseen that the valve is normally closed, thereby shutting off the waterto'the water motor, so that the suction fan is inoperative, but thatwhen the seat cover of the water closet is raised so that the closet maybe used, cam 11 will open the valve, so that water may flow to the watermotor, and thereby rotate the suction fan for. drawing foulair from thecloset bowl through chamber 12.

It will be apparent that various changes may be made in theconstruction, combination, and arrangement of parts as thus described,without departing from the spirit of the invention. 7
